After an extended period marked by frequent pauses, the work on my car is finally complete.

Everything that I outlined in the original post has been completed.

For your interest, I have attached the dyno chart for the engine with the 10.5:1 pistons and the 104/107 cams. Carbies are Dellorto. The power figure on the chart is rear wheel power. The engine is still very fresh. Once I have put some miles on it I think I'll be looking to make the tune a little more aggressive. Time will tell.
